San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

What Are Some Home Remedies To Get Rid Of Rats And Keep Them Away?
The moment you stumble upon rats in your home, you automatically switch into panic mode, simply because you know the menace associated with having these rodents around you.
Apart from damaging your home, rats contaminate your environment and expose you to several diseases. If you want to get rid of the rats in your home, there are some home remedies that you can use to achieve what you want. Here are some home remedies that you can try:
1. Peppermint Oil
To humans, peppermint is refreshing. But to rats, nothing can be more nauseating than it. To take advantage of this, all you have to do is put droplets of peppermint oil along the routes of the rat in your home or dip cotton balls into peppermint oil and drop the soaked cotton around places the rats frequent the most. The smell of this will keep them away because they won't be able to stand it.
2. Plaster Of Paris And Cocoa Powder
This is one of the best natural ways to get rid of rats. In this case, all you need to do is to mix plaster of paris with one tablespoon of cocoa powder and then sprinkle the solution along their routes. This mixture will suffocate and dehydrate the rats and make them run outside your home.
3. Onions
The good part about the use of this particular home remedy is that it is readily available in every home. To use this as a rat repellent, all you have to do is to place an onion bulb around the holes of the rat. The smell coming from the onion will make the rat feel uncomfortable and this will make them leave in no time.
